@addpowr the general conclusion was that the pixels are currently small enough that it's not able to be detected by the human eye. So it's more marketing than practicle benifit. Many say that improving contrast and color depth has a bigger impact than increasing resolution beyond 4K.
However, If budget allows and you’re building a serious home theater, you could pick an 8K TV now, with the mindset that you’ll get more “future benefit” as 8K content becomes more common.
